 - Day three of CGSpace AReS meeting in Amman
-  - We discussed CGcore and decided some action points
+  - We discussed CG Core 2.0 metadata and decided some action points
   - We discussed branding of AReS tool
+- Notes from our CG Core 2.0 metadata discussion:
+  - Not Dublin Core:
+    - dc.subtype
+    - dc.peer-reviewed
+  - Dublin Core, possible action for CGSpace:
+    - dc.description:
+      - We use dc.description.abstract, dc.description (Notes), dc.description.version (Peer review status), dc.description.sponsorship (Funder)
+      - Maybe move abstract to dc.description
+      - Maybe notes moves to cg.description.notes???
+      - Maybe move dc.description.version to cg.peer-reviewed or cg.peer-review-status???
+      - Move dc.description.sponsorship to cg.contributor.donor???
+    - dc.subject:
+      - Wait for guidance, evaluate technical implications (Google indexing, OAI, etc)
+    - Move dc.contributor.author to dc.creator
+    - dc.contributor Project
+      - Recommend against creating new fields for all projects
+      - We use collections projects/themes/etc
+    - dc.contributor Project Lead Center
+      - MELSpace uses cg.contributor.project-lead-institute (institute is more generic than center)
+      - Maybe we use?
+    - dc.contributor Partner
+      - Wait for guidance
+      - MELSpace uses cg.contibutor.center (?)
+    - dc.contributor Donor
+      - Use cg.contributor.donor
+    - dc.date
+      - Wait for guidance, maybe move dc.date.issued?
+      - dc.date.accessioned and dc.date.available are automatic in DSpace
+    - dc.language
+      - Move dc.language.iso to dc.language
+    - dc.identifier
+      - Move cg.identifier.url to dc.identifier
+    - dc.identifier  bibliographicCitation
+      - dc.identifier.citation should move to dc.bibliographicCitation
+    - dc.description.notes
+      - Wait for guidance, maybe move to cg.description.notes ???
+    - dc.relation
+      - Maybe move cg.link.reference
+      - Perhaps consolodate cg.link.audio etc there...?
+    - dc.relation.isPartOf
+      - Move dc.relation.ispartofseries to dc.relation.isPartOf
+    - dc.audience
+      - Move cg.targetaudience to dc.audience
 - Something happened to the Solr usage statistics on CGSpace
   - I looked on the server and the Solr cores are there (56GB!), and I don't see any obvious errors in dmesg or anything
   - I see that the server hasn't been rebooted in 26 days so I rebooted it

+- Send reminder to Atmire about purchasing the [MQM module](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=657)
+- Trying to decide the solid action points for CGSpace on the CG Core 2.0 metadata:
+  - dc.description → cg.description.notes
+  - dc.description.abstract → dc.abstract
+  - dc.description.version → cg.peer-reviewed (or cg.peer-review-status)
+  - dc.description.sponsorship → cg.contributor.donor
+  - dc.contributor.author → dc.creator
+  - dc.language.iso → dc.language
+  - cg.identifier.url → dc.identifier
+  - dc.identifier.citation → dc.bibliographicCitation
+  - dc.relation.ispartofseries → dc.relation.isPartOf
+  - cg.targetaudience → dc.audience
+- It's actually difficult to decide some of these because the current CG Core 2.0 document does not provide guidance or descriptions
+- Also, there is not a good Dublin Core reference (or maybe I just don't understand?)
+- Several authoritative documents on Dublin Core appear to be:
+  - [Dublin Core Metadata Element Set, Version 1.1: Reference Description](http://dublincore.org/documents/dces/)
+  - [DCMI Metadata Terms](http://www.dublincore.org/documents/dcmi-terms/)
+- And what is the relationship between DC and DCTERMS?
+- DSpace uses DCTERMS in the metadata it embeds in XMLUI item views!
+- We really need to look at this more carefully and see the impacts that might be made from switching core fields like languages, abstract, authors, etc
+- We can check WorldFish and MELSpace repositories to see what effects these changes have had on theirs because they have already adopted some of these changes...
